PIPE CLEANER Filed July 18, 1938 Inventor William 622v 272/5070 A fibrneys Patented Dec. 19, 1939 UNITED STATES PATENT OFFICE PIPE CLEANER William G. Evenson, Bamboo, Wisi Application July 18, 1938, Serial No. 219,860 1 Claim. (01. 131 -246) The present invention relates to new and useful improvements in cleaners particularly for smoking pipes and has for its primary object to provide, in a manner as hereinafter set forth, a

device of this character embodying a novel construction, combination and arrangement of parts through the medium of which a pipe bowl may be easily and expediently cleaned.

Other objects of the invention are to provide a pipe cleaner of the aforementioned character which will be comparatively simple in construction, strong, durable, highly eflicient and reliable in use, compact, light in weight, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters designate corresponding parts throughout the several views,

and wherein:

Figure 1 is an elevational view of my invention.

Figure 2 is a vertical sectional view of the invention, taken substantially on the line 2--2 of 5 Fig. 1.

Figure 3 is a transverse sectional view of the invention, taken substantially on the line 3-3 of Fig. 1.

Figure 4 is a fragmentary elevational view of 30 the invention.

Figure 5 is a vertical sectional view of the invention, taken substantially on the line 55 of Fig. 1.

Referring now to the drawing in detail, it will 5 be seen that the reference numeral 6 designates generally the body of the cleaner. The body 6 includes complementary members I and 8 each of which may be stamped or otherwise formed from metal or other suitable material. The lower 40 end portions of the members I and 8 are substantially semi-cylindrical in cross section to form heads and are stamped or pressed to provide projections 9 on their outer surfaces. The lower semi-cylindrical head portions of the mem- 45 hers I and 8 are provided on their inner side edge portions with tapered notches Ill and H, while the upper end portions of the members i and 8 are substantially plate like or flat and are formed into a winged handle l2 which secures 50 the sections 1 and 8 together by riveting or otherwise as shown at 53 in Figure 5 of the drawing. Each of the sections I and 8 in that portion constituting the handle l2, has formed therein a channel [2' for the reception of a screw 5 threaded actuating member M.

The screw threaded member I4 is of uniform diameter throughout and has its upper end portion fashioned into a knurled head I5 which may be grasped for turning the same. The lower end portion of the member I4 is threaded while the 5 portion intermediate the threaded lower end portion and head I5 is smooth and is journalled in the bearing I6 formed by the channels l2. A collar I7 is mounted on the screw threaded member [4 intermediate the ends thereof and is secured thereto by a pin I8 passing through the collar I! and. member M.

A nut l9 provided with diametrically disposed projections 20 and 2! is adapted to be threaded onto the screw threaded member M.

The operation of the device is thought to be manifest but may be briefly described as follows:

The lower end portion of the device which is composed of the semi-cylindrical members 1 and 8 is inserted into a pipe bowl. The screw thread- 20 ed member [4 is then turned by grasping the knurled head [5 and rotating same to cause the nut l9 to be moved in a downward direction on the screw threaded member It. On its downward travel the nut is prevented from rotating by the projections 20 and 2| which are projecting through the openings formed by the tapered notches in and H. The projections 2!} and 2! of the nut l9 while riding down the tapered notches l0 and II cause the semi-cy indrical sections to be forced apart and adjusted to contact the interior wall of any size pipe bowl. The device is then rotated by means of the handle l2 to effectivelyand easily clean substantially all or a portion of the cake in the pipe bowl.

Although I have shown and described here n a preferred embodiment of my invention, it is to be definitely understood that I do not des re to limit the application of the invent on thereto. and any change or changes may be made in the 40 materials and in the structure and arrangement of the parts, within the spirit of the invention as claimed.

What is claimed is:

A pipe bowl cleaner comprising a pair of complementary members each formed of a single piece of material and each including an elongated part of semi-cylindrical shape in cross section and a substantially flat part having wing forming portions, rivets connecting the wing forming portions of the two members together, the rest of the two members being disconnected from each other, the central portions of the flattened part being bent outwardly .into semicircular shape in cross section, the two semicircular portions forming a bearing, a shaft journaled in the bearing and having a handle at its outer end, a nut member threaded on the inner portion of the shaft, said inner portion of the shaft being threaded and the edge parts of the semi-cylindrical portions of the two members having tapered notches therein and projections on the nut extending into said notches for forcing the two members apart when the nut member is moved in a certain direction by turning movement of the shaft.
